| weightlessness | Condition in which no acceleration, whether due to gravity or any other force, can be detected by an observer within a system. It also means the absence of weight or the absence of the force of gravity acting on a body. Microgravity, gravitational force between 0 and 10 -6 g, is included here. (12 Dec 1998) |

| weightlessness countermeasures | Techniques and routines designed to prevent or reverse unwanted effects of weightlessness experienced during actual and simulated space flight, including physiologic changes related to removal of gravitational loading. Specific measures include creation of artificial gravity, exercise, low-level lower body negative pressure, and use of anti-deconditioning devices. (12 Dec 1998) |
| weightlessness simulation | Condition under normal earth gravity where the force of gravity itself is not actually altered but its influence or effect may be modified and studied. (12 Dec 1998) |

Weightlessness is the experience (by people and objects) during freefall, of having no apparent weight. This condition is also known as microgravity (see below). Weightlessness in common spacecrafts is not due to an increased distance to the earth; the acceleration due to gravity at an altitude of, say, 100 km is only 3% less than at the surface of the earth. ...

Amusement park rides often produce sensations of weightlessness. These sensations result when riders no longer feel an external force acting upon their bodies. At the top of the tower of a free-fall ride, a 100-pound rider would feel 100 pounds of force from the seat pushing as an external force upon her body. The rider feels her normal weight. Yet, as she falls from the tower, the seat has fallen out from under her. ...
